Last Words of a Killer: Seung-Hui Cho's Shocking Diatribe

In a package to NBC, Cho offered his own distrubing profile.

Excerpts From the Tape Cho Sent to NBC News

In his accompanying video, he explained his vicious actions: "You had 100 billion chances and ways to have a voice today but you decided to spill my blood. You forced me into a corner and gave me only one option. The decision was yours. Now you have blood on your hands." These were just some of the chilling words Cho recorded at least six days before his killing spree Monday. (NBC/AP Photo)
